Rolf, that link was posted before and fortunately no one paid attention to it. The page is so full of crap that the only thing it deserves is a good laugh while trying to figure whether the author is a *BSD troll or just plain stupid.
To be fair though, I think two or three of his points are correct and represent real problems with Linux. That does not mean that "Linux sux", neither that "*BSD rox".
Anyway, this is getting way offtopic. I invite interested parties to a plain old email flame 😉
